Hi again,

#1 I'm calling the new IDL 8.0 plot feature object plot has an
official name has been found for this guy ? :-)
#2 I'm creating a very simple plot
> _p = plot(indgen(10))
but now I want to very quickly display another using the same _p
window. Closing this one and creating a new one won't work because I
need to do this at a very high rate.

To get the full story, I have an application that shows a 2d image
(using tvscl). When the user moves his mouse over this image, the z vs
x and z vs y are plotted in 2 differents plot objects.

I tried to use _p.select and _p = plot(<new plot>) but this plots the
new data on top of the old one.

Am I missing something here ?

Thanks for your help

Jean
